Posted: Tue Sep 08, 2009 10:40 am Post subject: What is the correct engine installed C/L height?
Subject says it all - fitted new rjes exhaust, all lovely and soooo much quieter than the previous lash up, but a bit close to the rear valance (8mm ish both sides) Does knock, but can't hear it, noticed this morning. Probably due to crashing along on rubbish roads.
Since I didn't install the EJ22, thought that I should check that it's sat at the correct height in the shell.
Note:This is in a T25.
Straight edge across chassis rails and tape measure to crank nose = ?

copied from my reply to the same question on club80-90:
8mm is closer than it should be. Is the exhaust fitted on an engine installed with an adaptor plate? If so, it will be around 16mm closer to the rear valanve than it was designed to be because of the adaptor plate thickness and the 4mm longer VW bell housing. I have had others fit them to engines installed with adaptor plates, and nobody has mentioned the box knocking on the exhaust.
There is no such thing as a crank height from the chassis rails as such, as the crank CL is not parallel to the chassis rails. However, the easiest place to measure from is the top of (highest point on) the black crank pulley which drives the alternator and aircon. It should be 81mm if the crank shaft centre line is the same as the VW installation. If it's any higher than that, you'll lose a lot of exhaust clearance. Hope that helps. _________________ Regards,

Sorry - the 81mm dimension was for a Syncro, and yours is 2wd. I'll blame being in a mad rush getting stuff ready for Vanfest when I replied for not realising at the time. I have never actually measured this dimension in a 2WD. In a 2wd the engine is 42mm higher at the engine mounts, so how does 39mm from the highest point on the pulley to the top of the chassis rails sound? _________________ Regards,
